SERVSWITCH™ MULTI

11.1.6VIDEO CAN BE SEEN BUT IS SUPERIMPOSED ON ANOTHER COMPUTER’S VIDEO

1.Make sure that no two ServSwitch Multis in your system are set to the same address.

2.Make sure that all of the Expansion Cards in the system are plugged in completely and that their connecting screws are tight.

11.1.7VIDEO BLANKS OUT UNEXPECTEDLY

1.Check your administrator timeout (see Section 9.3.2.A) and/or keyboard/mouse-inactivity timeout (see Section 4.2.2) and make sure that both are set properly.

2.Make sure that neither your monitor, the selected computer, nor any of the ServSwitch Multis in between have lost power.

3.Make sure that the video cabling between the monitor and the selected computer has not come loose or been cut somewhere.

11.1.8THE ON-SCREEN DISPLAY DOESN’T APPEAR

1.Make sure that the User-Interface Card to which your console is attached is in fact a UICD rather than a UUIC.

2.Try getting the Command-Line-Entry Window to appear (see Section 9.2.4); if you can, make sure that you don’t have menu activation turned OFF (see Section 9.2.3.B).

3.If your monitor is not a multisync type, and if you haven’t already done so, enable the UICD’s non- multisync-monitor support (see Section 9.5).

11.1.9AN RS/6000 KEYBOARD IS NOT RESPONDING

Some RS/6000 computers have difficulty if they’re connected to their keyboards through a ServSwitch Multi system. Temporarily uninstall the CPU-Interface Card that the RS/6000 is attached to. Find the jumper on the Card labeled “S5”; set this jumper to ON and reinstall the Card. If this doesn’t help, take the actions recommended in the next section.

11.1.10A KEYBOARD DOESN’T WORK

1.Send the Command-Mode hotkey sequence (see Section 8.2.1) to the ServSwitch Multi from the keyboard. If this sends the Switch into Command Mode (the LED for your current channel should blink), at least the keyboard and Switch are communicating, so the problem is likely on the computer side; skip to step 5. If the Switch won’t go into command mode, go on to step 2.

2.Make sure that the keyboard is completely and securely plugged into the User Cable, and that the User Cable is completely and securely plugged into the ServSwitch Multi. (If your User Cable is a PS/2 type, make sure that the keyboard and mouse strands haven’t been connected backwards at either end; the PS/2 mouse strand is marked with a yellow band.)

3.If you have multiple keyboards attached to your local console or your secondary console’s User-Interface Card, the ServSwitch Multi doesn’t support this; you’ll have to remove all but one of the keyboards.

4.Is Scroll Lock ON or OFF? This will determine which of two characters is sent to the selected computer when certain keys are pressed; see Section 8.4.

5.Make sure the selected computer is plugged in, turned ON, and receiving adequate power.
